Otd boundary variations in wt and nej embryos. Shown are average normalized Otd profiles for wt (green) and nej (magenta) embryos at early nuclear cycle 14 as a function of x/L. Error bars show standard deviations of Otd intensities. (Inset) Measured positional error WOtd/L and WHb/L (the standard deviation of measured threshold positions) of the Otd and Hb boundaries for both wt and nej embryos.
